Drivers traveling between Antioch and Brentwood on Lone Tree Way should expect delays Tuesday and Wednesday night.

The contractor for a project to widen Highway 4 and add on- and offramps at Sand Creek Road will be working on a new highway bridge over Lone Tree this week, according to a Contra Costa Transportation Authority news release.

To ensure worker safety, one lane in each direction of Lone Tree will be closed between Jeffery Way in Brentwood to Canada Valley Road in Antioch from 8 p.m. to 5 a.m. on both nights.

Two lanes will be open in both directions.

Motorists are advised to expect some delays and allow extra travel time.
